Set Baud Rate Field in Control Register

Code

#include <stdio.h>
#include <stdint.h>

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    // Your code here
    //for position starts at 8. bit for 4 bit space
   
    //we clear with 4 bit mask
    reg &= ~(0x0F<<8);
    //we set new baud rate
    reg |= ((baud & 0x0F)<< 8);
    //
    return reg;
}

int main() {
    uint32_t reg;
    uint8_t baud;
    scanf("%u %hhu", &reg, &baud);
    printf("%u", set_baud_rate(reg, baud));
    return 0;
}
